At some point in the not-too-distant future, Blizzard plans to release its highly anticipated card game Hearthstone: Heroes Of Warcraft on the App Store. Before that happens though, the game will be officially released for the PC - and having spent some time getting stuck into the game's superb strategic card combat ourselves, let's just say you'll want to get some practice in ahead of the iPad launch.

Hearthstone is currently in closed beta, and Blizzard is offering 100 Modojo readers the opportunity to join the PC crowd who are already playing and testing the game. In order to be in with a chance of winning one of these beta keys, head over to Modojo and fill out a short form. Good luck!
